Create a .dockerignore file to ensure that any files related to a local
build do not affect the container that you build for deployment.

Dockerfile
README.md
vendor

Create a new file, service.yaml and copy the following service definition
into the file. Make sure to replace {username} with your Docker Hub
username.

After the build has completed and the container is pushed to docker hub, you
can deploy the app into your cluster. Ensure that the container image value
in service.yaml matches the container you built in the previous step. Apply
the configuration using kubectl:

kubectl apply --filename service.yaml

Now that your service is created, Knative will perform the following steps:

Automatically scale your pods up and down (including to zero active pods).

To find the IP address for your service, use these commands to get the
ingress IP for your cluster. If your cluster is new, it may take sometime for
the service to get asssigned an external IP address.
